The Undo command allows you to cancel the last command that changed the item. The Status/Command Line prompts:
UNDO last change?:N
Press Y to execute the Undo command.
Press N or press RETURN to cancel the Undo command.
Example
00022 PRINT (10,10)TEXT
Note the current cursor position. Assume that you want to insert a colon (:) at the cursor position to give proper syntax to the DataBasic statement. You forget that you are not in Insert Mode and type a colon. A colon is the Truncate Line command, and the line is now:
00022 PRINT (10,10)_
Press U. The Status/Command Line prompts:
UNDO last change?:N
Press Y. The line is restored to the original as follows:
00022 PRINT (10,10)TEXT
